EARL G. WATROUS, OF CHICAGO, ILLINOIS.

BASIN-COCK.

To all whom t may concern:

Be it known that I, EARL G. i/Viirnous, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Basin Cocks, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates more lparticularly to that class of basin-cocks in which the valve is opened by depressing a push-buttoii located in the top of the casing, and it has for its object the increased simplicity and eiiiciency of basin-cocks of this character.

In the accompanying drawings, Figure l is a middle vertical section of my improved basin cock in the plane of the spout, the depending threaded stem of the cock being left in elevation; Fig. 2 is an approximately middle vertical section at right angles to that in Fig. l, the view deviating from an exact middle vertical section sufficiently to pass through the pivotal supports of the lever through the medium of which the valve is lifted from its seat by depressing the pushbutton, as indicated by the dotted lines 2-2 of Fig. l; Fig. 2 a detail view of the lever intermediate the stem of the push-button and the valve-carrier for causing the lifting and opening of the valve when the button is depressed; Fig. 3 is a front elevation of the complete basin-cock, with the spout cut away to expose the delivery end of the watei passage leading into the same; and Fig. 4 a detail perspective view of the cage which carries and guides the valve and through the medium of which the valve is lifted from and restored to its seat.

The same let-ters of reference aie used to indicate corresponding parts in the several views.

The casing of my improved basin-cock comprises a body portion A having a ianged base B and depending threaded stein C and spout D, cast in one piece, and a cap piece E. The upper end of the portion A of the casing and the lower end of the cap E are internally threaded andengaged by an eX- teriially threaded ring Gr whose inner sui'- face forms a guide for the cylindrical upper end of an open-sided valve-carrying cage H, v

whose contracted lower end is formed into a cylindrical guide I which fits in a corre- Speccation of Letters Patent.

spoiiding guide-way formed for it in the bodyof the casing and carries upon its under side the valve J. The valve J normally rests upon a seat formed for it in the flanged base of the casing at the upper end of the central passage through the stem C, and serves to control communication between said central passage and an annular cham- -ber K formed in the base of the casing, said chamber K being separated from the interior of the body portion A of the casing above it by a horizontal diaphragm or partition formed in the casing and provided with a central cylindrical opening in which the guiding member I of the valve-carrier H fits and travels. The chamber K communicates with the spout D through an internal spout or passage L formed in the casing. A coiled spring M surrounds the cage H beu iieath the threaded ring Gr in which its upper end is guided and bears at its lower end against outwardly projecting lugs or anges a formed upon said cage, Fig. et, said spring thus serving to press the cage H downward and yieldiiigly hold the valve J to its seat. Then the cage and valve are lifted, against the resistance of said spring, the water passes from the stem C into the chamber K in the base of the casing, and thence through the passage L to the spout I).

from a short rock-shaft or pair of trunnions T, Fig. 2a, resting at its outer ends in suitable U-sliaped bearings V V provided for it upon the inner faces of the sides of the` body portion A of the casing, Fig. 2. The rearwardly extending arm S of the lever projects through and plays up and down in' a vertical slot b in the rear side of the cage H, while its forwardly projecting arm S extends through a shorter slot c in the front side of the cage H, Fig. 4, immediately be- Patented Nov. 8, 1910.

neath the upper' end of such slot, so that when the rear end of the lever S is depressed and its forward end S thereby lifted said forward end of the lever will carry the cage H upward with it and Vlift the valve J from its seat. The rear end of the lever S is depressed, to thus lift the valve from its seat, by depressing the push-button N, the spring M resisting such movement of the parts and serving to restore them to normal position when the pressure upon the pushbutton is removed.

The downward pressure of the spring M upon the cage vH may be regulated as desired by turning the threaded ring G in one direction or the other, and will be preferably so adjusted as to be just sufficient to overcome the pressure of the water against the under side of the valve J and normally hold the latter to its seat, so as to offer a minimum resistance to the downward movement of the pushbutton when the latter is depressed to open the valve. p

The pressure of the water in the chamber K, after the valve J has been lifted from its seat, acting upwardly upon the under side of the valve J and the surrounding area ofthe cylindrical guiding' member I which carries the valve, will serve to assist the downward pressure upon the push-button N in maintaining the valve in open position. This water pressure in the chamberK will be governed, under any given pressure in the supply pipe leading to the cock, by the relative sizes of the inlet passage to said Vchamber through the stem C and the outlet passage L leading therefrom to the spout D, and may be increased as desired byreducing the size of the latter passage relatively to the former.

The discharge of the water through the internal spout or passage L into and through the spout D produces an ejector action or effect, which results in drawing outward into the spout any water which may pass into the interior of the body portion A of the casing, around the guiding member I or otherwise, so that there is no tendency whatever for vthe water to escape through the upper part of the casing, and no stuffing boxes or tight oints are therefore necessary.

As will be understood from the foregoing description, I have produced a simple and efficient basin-cock of the character described, in which the valve and the push button for opening it are located centrally of the cock and in axial line with each other, in which depression of the push-button serves to lift the valve and open it in the direction of the water pressure and against the regulated pressure of a spring and in which the valve is closed by such spring against the water pressure when pressure on the push-button is relieved, and in which the discharge of the water through the main spout of the cock serves to effectively drain the interior of the casing and render tight joints and stu-lling boxes unnecessary.

Having thus fully described my inven tion, I claim:
